Digital potentiometers (dpots) are ubiquitous components available in a variety of packages, resistances, and resolutions. However, few implement anything but the usual linear function of resistance ...

Catalyst Semiconductor’s CAT5116 is a new Digitally Programmable Potentiometer (DPP™) integrated circuit (IC) for the audio and optical equipment markets. The CAT5116 features a 100-tap, log-taper ...

[Stephen Woodward] is familiar with digital potentiometers but is also familiar with their limitations. That spurred him to create the PWMPot which performs a similar function, but with better ...

A pair of Digitally Programmable Potentiometers (DPPs) feature 256-posiion resolution and I2C and Serial Peripheral Interface (SPI) Bus connectivity. The CAT5171 and CAT5172 are single-channel ...

The human eye's highly nonlinear response to light levels poses problems for designers of adjustable lighting. Simple hardware or software linear-control methods compress most of the apparent ...
